Hi,
I have just purchased 64 GB Class 10 Samsung micro SD card with a SD adapter and USB adapter.
I plugged it in to my S4 and everything seemed OK. Copied all of the contents from my old SD. Everything was working fine until I restarted my phone. After restart all of the files were present by could not access them. Some of the files and folders had ~ as prefix. Plugged the card in my PC and the files were corrupted. Recopied everything and tried several times again. The same outcome. Reformatted the card to exFAT and to FAT32 both from my phone or my PC using several available programs. No success. Whenever I unmount the SD card or restart the phone the files get corrupted. So I figured the card is broken. So I decided to test it only on my PC. Copied lots of stuff to it (music, movies etc.) and started using it on my PC. I have mounted/unmounted it on my PC probably 100 times and it works just fine. So that means that the card is fine (or am I wrong???). Also tried it to plug it with the usb adapter into my TV. It says that usb disk is empty.
The files only seem to get corrupted when I place the card in my S4 and unmount it/restart the phone. The card works just fine on my PC.
Does anyone else have this issue?
I am running a rooted 4.3 Android OS.
Thank you!
You have to partition the card into 32GiB chunks. So make two, 32GiB partitions and it will work fine in your S4, except it will show you have two external sd cards.

If you don't want to make two seperate partitions on your external microSD card then do the
following:
Remove your external microSD and plug it into a card reader and or the adapter which came
with the card then plug it into your computer.
Make an empty folder on desktop of computer and copy all files and folders from the microsd
card into the empty folder.
Format your external microsd using this windows utility and copy all the files/folders back onto
the card from your computer and replace it into your phone.
Here is the direct download link for this fat32 formatter which is a windows utility:

By doing the above your external microSD card should work fine in your phone.
Good luck!

Thank you for your reply. I did as you suggested and it worked for some time. I mounted/unmounted several times and it seemed fine. Then did a restart and the files were corrupted again.
Why does the card need to be divided in 2*32GB in the first place? Isn't the S4 suppose to support 64 GB cards?
Your suggestion seemed to isolate only part of the problem. It remains only the restart. What can be associated with corrupting data on sd card and android restart?

Thank you for your reply. Unfortunately it didn't work. I tried similar thing with other software also (Minitool partition wizard, Panasonic SD formatter, etc.). When I unmount/mount or restart data corrupts

No, it depends on your kernel if it supports a certain FS. I am not sure why your files are being corrupted other than one, your ROM isn't unmounting your card properly on restart or two, your card has issues. Again, I am not sure.

In that case do you suggest I try changing kernel? Do you think that might help? My kernel version is 3.4.0-2082040 if that means something. Do all S4s come with the same or different kernel? Will it help If I unroot or maybe install other ROM for different country or different operator?

All the stock S4's come with the same kernel, so if your S4 is stock then it's not a kernel issue.
Have you tried any other external microsd cards, if not that's what I would do next.
Most of the better microsd cards have either a 2-3 year or a lifetime warranty.
Good luck!
I currently use my old 8GB sd card with no problems whatsoever. My S4 is rooted. Does that change the kernel? Should I unroot?

Hi guys,
I have a 32g class 10 sd card I bought to use instead of my 16gb class 2 but I have been facing quite some issues in the last couple of weeks
I took the 32g, put it in my win7 PC, formatted it to FAT32, safely removed it and now the arc doesnt recognize it... I just wanted to format it via the settings-> storage -> erase card in order to make sure everything is all peaches and cream before loading 20+gig of music in it.
...
All I want to do is finally transfer all my music (24ish gig) to the new 32g , and back up all my apps and stuff via Titanium Back Up pro.
Simply said, I want to have my 16g card data in my 32g one , with all my beat
Please could someone share some tips or links, I'll do homeworks and have been, but I have been facing so many complications since the last few weeks
Thanks in advance
Does your phone recognize another card properly?
Did you apply a volume name when formatting the 32GB card?
Did you try the 32GB card in the phone before formatting it?
I've done pretty much the same as you with a 32GB card (Kingston Class 4) and had no problem.
Are you sure the 32GB card is good and not a counterfeit?
Try formatting it again to with FAT32, default parameters, short or no volume name. Try copying your files to the card on the PC to see if it actual works.

Thanks I did put a volume name. That might explain it.
Yes the card already worked ( plenty of times ). I have been trying numerous time to transfert the music ( takes forever to transfer 20gig to an SD card , even class 10... ), and had mixed results that always ended up failing ( most of the times because of me... like forgeting to safely remove the sd card from my laptop made the card unrecognizable by the phone afterward...of course I just finished to tranfers the 20gig and was too happy to safely remove it... )
I will try that right now. thanks again
*EDIT*
Bah still same problem I must be doing stupid... SD card is not recognized by the phone. In the settings menu ( storage ) I cannot mount or unmount it and thus format it via the phone itself
That even after reformating it to default FAT32 partition with no volume name using MiniTool Partition Wizard Home
So number 1 priority is getting the SD card to be recognized again by the phone
**EDIT2**
When browsing the card with astro it says problem creating external cache , with root explorer it only says directory is empty. Still can't do anything in the settings menu
Obvious statement, but did you set it to primary?

Or format it wrong, Arc will say it's damaged and say that it has to format it to detect it.
Should fix it, too.

Ya I'd love to get to this point ( which I got in the past hehe ) but at the moment it's still not even recognizing the sd card anymore
still formating btw....
How did you recover your issue?
I think I have a similar SD card problem. But, I encountered it after I did factory reset with SD card erase option selected. I didn't do anything after all. When I connect to PC, on the phone upper bar, there is no notification regarding USB. The middle button seems not working either.
Try formatting the card with this Panasonic SD/SDHC/SDXC Memory Card formatter.
That's strange why not just do a quick format in Win7 or WinXP, to FAT32? I use a 32GB as well and Arc has no issue with it. Coming from the 8GB, here's what I did.
1. Take off the 8GB from the Arc and placed in a USB reader.
2. Copy off all the files to your PC. I used WinRAR to accomplish this, just archive everything and STORE it (no need to compress so operation is faster). Or you can just use drag and drop plain copying its all the same.
3. Analyze the copied files and remove all unneeded bloats (ie. old movies u don't intend to watch anymore, clear out useless temp files, etc)
4. Copy back the files on your new FAT32 formatted card using the USB reader, then put in your Arc.
If you notice, the entire data migration is done via card reader/USB. Using the Arc as such will slowdown your progress and introduces unnecessary delays.
You can also use usb tool, it basicaly creates a back up image and can be restored to the new sd

Having an issue with my T-Mobile S4. Starting yesterday after resetting my phone freezes up after I insert an SD Card into it. I leave the SD Card out and the phone runs fine, pop in an SD Card and it freezes up after about 5 minutes. I have reset the phone completely and I am still having the same issue. I have tried different SD Cards that I have and the issue still happens on each SD Card. I originally was using a 64 GB sd card and I transferred the files to each SD Card, so my question is, is it possible that a file on the SD Card is corrupted and causing this issue or is there something else going on? I have a lot of other things I could try to do to narrow it down I know but I figured I'd throw this up there to see if anyone has had this issue also.

Have you ever tried to remove the SDCARD and plug it into a card reader or into the computer and copy all files and folders
from the card to an empty folder on your computers desktop.
After that format the 64GB microsd using FAT32 in your Windows computer.
Then put it back into the phone as a blank empty sdcard.
Then check out the phone and see if it has any issues with the sdcard. Chances are excellent that doing that will fix the problem.
If it does you can copy all the files and folders from your computer back to the sdcard in the phone.
Good luck!
I have 2 64gb sandisk 10x microsd with Samsung S4 I9005 with Android 4.3. I formatted with android, also Windows 7 64bit with various types of sizes on laptop. However on laptop or on phone after writing some files and disk scanning, it gives many disk errors. Even after scancheck and correcting it.The errors repeat each time. I wonder if it is software or microsd hardware problems. There is no problem with 32 gb sandisk microsd.

I have a rooted AT&T S3 running JellyBam 9.2
Basically what happened is after rooting my phone, my 64gb ADATA microSD card stopped letting me copy files to it while it is plugged into my computer through my phone. It would copy over about 100 mp3 files from my computer before a window pops up and says that the device has stopped working or has been disconnected. Then, I unplug my phone from the computer and try to reboot it, but it just hangs at the "Rebooting phone..." window. This only happens after the SD card messes up, all other times the reboot is fine. After I pop the battery and resume copying files, it starts to work again, but then stops after another few mp3's. The files that did manage to get copied over, however, are able to be seen and scanned by my file manager and my music app. The SD card, when plugged into my laptop through an adapter, is able to copy and read files perfectly fine. Can anybody shine some light on what is wrong and possibly how to fix it? Thanks
First you need to format the card to fat32 and then copy your files from the computer directly onto the card through a card reader not the phone Samsung has some issues with exfat which is the way the card are originally formatted. There are a number of free programs out there to format your card, hope this helps

The exFAT filesystem is proprietary. Samsung developed their own version, rather than license it from Microsoft.. and the Samsung version is known to be buggy. As jimchee explained, what you need to do is reformat your memory card to a FAT32 filesystem to ensure that it is stable.
PLEASE HELP with 64gb sd in GS3!

I rooted my sprint gs3...now it won't read my card! all data is still there as I checked it on my laptop!
it recognizes the 16gb card i put in to test!
What can I do? do i need to totally reformat? UGH!
Total newbie to this stuff and need this working!
Also...if anyone knows...can't use wireless tether as it says "phone is in an unknown state"!
HELP would be MUCH appreciated! THANKS!
I'm using a 64GB Sandisk micro sd card. Running wanamlite v4.0.
I can't seem to delete or add files to my memory card. Every time I delete or add a file and restart my phone, either the added file is gone or the deleted files are back. Tried formatting multiple times with different softwares. Files all still return back. I also ran some diagnostic tests and they all came back error free.
I have also 64 gb micro sdxc sandisk card. But no problem with that. I have kept extFAT partition.
Try on different phone and check for same problem.

I also have the same problem, stuck it in my brothers galaxy s3, did reformat, but it stays the same, same files are still on it. can't delete or add any new files to the card. it seems stuck or something. i did use twrp to wipe it as well but says succesfull upon reboot still the same.
(partial change) i actually can add files to it sometimes, even through my computer, but after a while which is random it seems or a reboot the files are gone.
I flashed a rom today and noticed that my music and pics disappeared. Went in with root explore and can see the file but it has no data size. The name and date everything is in place but the music and pic. Did it twice different roms. Anybody have a answer for this?

Have you removed the external sdcard and plugged it into a card reader or adapter
and into your computer yet? There is a chance that all is good, if it is you need to
copy all files and folders from from the card to computer as a backup.
Another thing you can try is to connect the phone using usb cable to your computer and
with the computer see if all the files look normal, if they do then again do the above.
If your external card is 32/64GB and has NOT been formatted using FAT32 format and
the files are unusable then you need to format it using your computer with a fat32
formatter. (free windows utility).
Here is the download link in case you need it: http://www.ridgecrop.demon.co.uk/guiformat.exe
I have seen external sdcards which got corrupted due to not being formatted with FAT32.
good luck!
